Abstract

The water-soluble fertilizer is prepared from the following raw materials in parts by weight: 17 to 50 parts of ammonium polyphosphate, 10 to 60 parts of organic potassium salt, 10 to 40 parts of urea, 1 to 5 parts of sodium octaborate tetrahydrate, 1 to 5 parts of EDTAzinc, 10 to 30 parts of glacial acetic acid, 1 to 5 parts of xanthan gum and 1 to 3 parts of tea polyphenol. According to the water-soluble fertilizer provided by the invention, all the raw materials are matched for use according to a certain proportion, so that the proportion of nitrogen, phosphorus and potassium and trace elements can be optimized, the microbial environment of soil can be improved, the utilization rate of applied nitrogen, phosphorus and potassium by crops is increased, and the yield-increasing effect of the crops is more remarkable. The invention also provides a preparation method of the water-soluble fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. Compared with traditional superphosphate, granulated compound fertilizer and other varieties, water-soluble fertilizer has obvious advantages. It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops. Using water and fertilizer at the same time, water and fertilizer are used to realize the integration of water and fertilizer. Its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80% to 90%. Moreover, the fertilizer effect is fast, which can meet the nutritional needs of high-yielding crops durin...
